tedu: when you commit a change with global impact, please do a full build to verify there's no fallout, machines are fast now and 1 hour of your time is worth saving a bunch of others 1+ hour of their time in this case, paths.h broke this as noticed by jmc and 3 of my build machines so far, but I might as well restart them all, so call it 8 machines impacted.
Use _PATH_DEFPATH if no PATH in the environment when invoked as which.
I am retiring my old email address; replace it with my OpenBSD one.
